Explorer NIR-128

Explorer NIR-128

The Explorer NIR series near-infrared spectrometer is designed using Hamamatsu's uncooled 128pixels InGaAs sensor. It is compact and lightweight, with a measurement spectrum range of 950-1700nm. It is cost-effective and is very suitable for plastic sorting, food testing, scientific research, and System integration. This series adopts a replaceable slit design, and one spectrometer can be configured with a variety of slits of different widths to meet the spectrum measurement needs of different resolutions and sensitivities.

Product advantages:
  • Using Hamamatsu uncooled 128 pixels InGaAs sensor, it has extremely low power consumption.
  • Compact optical path and structural design, suitable for system integration.
  • It has an interchangeable slit design that can be matched with slits of different specifications. Users can choose different resolutions and sensitivities to meet the needs of experiments.
  • The wavelength range and resolution can be customized to configure the appropriate spectral range and resolution.
  • Professional measurement software, providing measurement functions such as absorbance/transmittance/concentration/reflectivity/timing monitoring.
  • Measurement of light sources from 950nm to 1700nm, including wavelength stability, intensity stability, and half-maximum width of the light source
  • Testing of freshness and sugar content of fruits and vegetables; testing of fat and protein content of meat; quality analysis of grains and seeds, etc.
  • Oil composition analysis
  • Life Sciences and Pharmaceuticals, Pharmaceutical Ingredient Analysis and Process Monitoring
  • Composition analysis, material screening and quality control of plastic product production process
